Miami hoped to make a big splash this season with the opening of its new ballpark, but the Marlins' record is 44-48, and they're in fourth place in the N.L. East. The Marlins' offense has been led by the mighty Giancarlo Stanton, but Stanton's out right now with knee surgery, and even with him for most of the year, the Marlins are still fifth-worst in the majors in runs scored, thanks in part to poor performances from catcher John Buck and first baseman Gaby Sanchez. They're also getting less than they probably hoped for from top free-agent acquisition Jose Reyes.
Their pitching, meanwhile, is tied with the Phillies for eighth-most runs allowed in baseball, thanks primarily to an awful bullpen that has been hurt by poor performances from Heath Bell, Edward Mujica and Chad Gaudin.
